Abstract

Ca_1-xSr_xFeO_3-z and SrFe_1-xCo_xO_3-z (0≤x≤1, z-0.1) of the cubic perovskite type were prepared by treating grossly oxygen-deficient samples at room temperature using an electrochemical oxidation technique. In the case of SrFe_1-xCo_xO_3-z, the ferromagnetic curie temperature has been found to be raised above 3 00K for 0.4≤x≤1.0 (340K at x=0.4) by the electrochemical oxidation method. Only a few hundred mV of electrode potential has relatively more oxidation power than a considerable high oxygen pressure, however, the lack of stability (drcrease of oxygen content) after electrolysis is a weak-point.
